AMPACT In-Line Disconnect Switch (ILD-II)
15 kV to 69 kV Class
KEY FEATURES
•Installation with standard
AMPACT tooling
•Quick, easy manual or hot-stick application
•Both mechanical and electrical connection made
simultaneously with the AMPACT tap
•No line tensioning devices
required for installation
•Double string of polymeric
insulators prevents rolling of the switch
•Copper disconnect blade
assembly suspended below the insulators simplifying the
cutting of conductor
The AMPACT ILD-II combines the reliability of copper blade components and a doublestring of polymeric insulators with the AMPACT deadend yoke assembly. The result is an in-line disconnect that can be installed without the need for tensioning devices.
The proven performance of AMPACT deadend technology has been utilized in the design of the AMPACT ILD-II. The deadend yokes are bolted to two (2)
polymeric insulators. The copper blade assembly is connected to the AMPACT
deadend yoke assemblies between and below the double string of insulators. This provides adequate space for cutting the conductor after installation of the
AMPACT deadend taps.
Standard AMPACT tap application procedures are used to make both electrical
and mechanical connections simultaneously. The AMPACT ILD-II can be installed
on standard stranded all aluminum conductors (AAC) or aluminum conductor steel
reinforced (ACSR) in conductor sizes from 1/0 to 954. In addition to its original
function, to help install the switch on the conductor, the uniquely designed eye
keeper doubles as a mechanical clamp to increase the conductor pulling-out
strength in excess of 7500 lbs without slipping or damage to conductor.

AMPACT In-Line Disconnect Switch (ILD-II)
The integral pulling eye on the body of
the AMPACT deadend yoke assembly
is provided to the attachment of line
tensioning devices if removal of the
AMPACT ILD switch is required. The
tensile rating of the pulling eye is 6,000 lbs, while the AMPACT dead-
end yoke assembly is rated at 10,000 lbs tensile.
Electrical ratings are provided in the
performance characteristic tables.
back, or if using the new keepers, it can
be cut flush on each end.
The unique AMPACT ILD design allows for positioning of cutters between the double insulator assembly. The conductor can be cut between the AMPACT deadend yoke assemblies and the ends bent • A load break tool can be used up to 35 kv utilizing the attachment
hooks provided.
